VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 358,878, dated lifarch 8, 1887.

Application led April 13, 1856. Serial Nu.l!18,097. (No model.)

To all whom t may concern:

Be it known that l, JACOB PFAU, a citizen of the United States, residing at Cincinnati, in the county of Hamilton, State of Ohio, have invented certain newand useful Improvements in VaponBurners, of' which the following is a specification, reference being had therein to the accompanying drawings.

Thisinvention relates to those burners which are attached to gasoline and other vapor' stoves or similar heating and cooking apparatus, and the object of the improvement is to furnish such burners with a device that will insure the proper filling of the cup 7 and at the same time prevent any accidental overflowing of the same. To accomplish this result I provide the burner with a special cup -.charger, which usually consists of a plug or cut-off` or other appliance that is capable of being shifted as occasion may require. Wlhen shifted or turned in one direction, the chamber of the plug is filled with `gasoline or other burningfluid; but when said plug is shifted or turned in an opposite direction this charge of iuid is emptied into the cup. Therefore, by making the capacity ofthe charger about equal to the capacity ofthe cup the latter can be filled with the proper quantity of duid to heat the burner preparatory to generating the gas therein, as hereinafter more fully described.

In the annexed drawings, Figure l is a side elevation of my improved vapor-burner, the handle of the charger being shown turned to permit the latter being filled with gasoline. Fig. 2 is a lfront elevation of the burner, the handles thereof being sectioned. Fig. 3 is an .enlarged longitudinal section of the charger,

the'port of' the same being shown in communication with the branch pipe. Fig. 4 is a transverse section taken through said charger in the plane of the branch pipe. Fig. 5 is a similar section in the same plane, but showing the charger in the act of emptying its contents into the cup of' the burner.

A represents an ordinary gasoline or vapor burner, having a depending tube, B, from which a side pipe, C, (indicated by dotted lines in Fig. 1,) extends to a valve-chamber, D, containing any approved form of' regulator.

E is the handle of this regulator.

F is a customary cup, attached to the lower end of Valve-chamber D, said cup being provided with a lip, G, for a purpose that will presently appear. Proceeding from this tube Bis a branch pipe, H, that communicates with a shell or casing, I, having a discharge opening or slot, J, and provided at one end with a pair of shoulders or other stops, K K', which arrest the lateral lug L of a plug or cut-ofi', M. This cutoff is adapted to be turned within the shell l by means of a handle, N, and is chambered at O, the capacity of said chamber being about equal to the capacity of the cup F.

I? is a port leading into this chamber o f the plug or other cut-oit'.

Vhen the burner is in its normal condition, the handle N is turned to the position seen in Fig. l, which act causes the lug L of plug M to come in contact with stop K of' casing I, as represented in Fig. 2. As aresult of this turningof the plug its port Pis brought in line with the branch pipe H, as seen in Fig. 4, thereby causing the chamber of said plug to become filled with gasoline or other burning iiuid; but the fluid cannot now escape, because the dischargeopening .I is closed. To start the burner the handle N is turned until the lug L comes in contact with the other stop, K', which act causes the port P of' plug M to be brought in line with said discharge-opening J, as seen in Fig. 5. Consequently the fluid contained in chamber O is discharged therefrom and falls onto the lip G, which sheds said iiuid into the cup F. rlhe iluid in the cup is then ignited and the gas generated in the burner in the usual manner.

From this description it is apparent that the chambcred plug acts as a cutoff` or charger that supplies the cup with sufficient fluid to generate the gas, thereby rendering it impossible to overflow said cup, unless the plug is repeatedly and intentionally turned,which can be guarded against by proper instructions furnished to the user of the stove or other appa ratus.

It is evident this invention may be modified by causing the cut-oli' to reciprocate within the casing and omitting the pipe H, in which event the inlet-port l) would open directly into the tube B.

I claim as my invention- 1. The combination of a vapor-burner, a

casing communicating therewith and having a discharge-port, a shiftable charger fitted Within said casing, and a charging-cup applied to the device, for the purpose described.

2. The combination of a vapor-burner, A. B, a casing, I, provided with inlet H and outlet J, a revolving plug, M, tted within said casing and furnished with a Chamber, O, and discharge-opening P, and a Charging-cup, F, ap-

[o plied to the device, for the purpose described.
